To all whom it may concern:

Be it known that l, GUSTAF ENAnsoN, a.v citizen of the United States, residihg' at Montclain-in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Bearings for Swings, of which'the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in supports for swings anCl IS particularly directed to the provision-of their upper ends.

bearing means for thesuspension members at It isthe object of the present inventiontdi provide means whereby the suspension mam bers of a swing may be pivotally secured at their upper ends in such manner that fric'.

tion will be to some extent eliminated with a consequent ease; of action and durablhty of structure.

It is a further object of the presentinvention to provide a structure wherein this bearing means may be associated with any desired form of support, as for instance, a transverse beam.

It is a; further object of the invention to provide a structure of this class which isbroken away in section to more clearly disbeam In the bearing provided, it is necesclose the structure. transverse sectional view taken through the journal member of the device.

Corresponding and like parts are referred to in the following description and designated in all of the views of the accompanying drawing by like reference characters.

Referring now more particularly to the drawing. there is shown a swing support v comprising a suitably supported horizontal sary that there be a cylindrical member to S pecificationpf'Letters Patent.

which it may be attached. Therefore, to provide this, a pipe section 6 is provided having at spaced intervals pairs of alining openings 7 through which a bolt 8 is passed, said bolt being also passed through a spacing block 9 disposed between the pipe section and beam and through the beam itself .where it is secured to a nut lO. The face of jthespacing block is concaved at 11 to receivethe pipe section whereby a firm and compact structure throughout is provided whichis at the same time of exceedingly simple design. 1

The bearing means whereby free pivotal connection of each of the suspension loops 12 is provided, comprises a sleeve member 13 ositioned on the nae section and havin b roller bearings 14-. disposed between it and the pipe section. The sleeve is provided with a lateral arm 15 having an eye 16 formed in.

its free end whereby the suspension loop may be readily attached. To prevent lateral displacement of the sleeve or of the roller bear- ,ings, a collar 17 is provided on each side of the sleeve. Each of these collars is provided with a set screw 18 adapted to engage the pipe to prevent movement of the collar relative to'the pipe, and each of the collars is provided with a lateral fiangef'l9 embrac ing the outer periphery of the sleeve to thus prevent dust or other foreign matter from entering between the collars and sleeves and engaging between the roller bearings. By the provision of these collar portions holding the sleeves, it will be seen that a very simple structure is provided while at the same time the sleeves may be disposed toward or away from each other to suit existing conditions. It maybe desired to associate these bearing members with a spring frame which is composed entirely, .or in which the transverse supportingv member is composed, of pipe In this case, it is obvious that it would not be necessary to provide a second cylindrical member to support the bearings, as the bearings could be applied directly to the said pipe section.

From the foregoing, it is observed that a very simple structure has been provided which may be readily attached in position on any swing support and which suspends the swing in a very effectual manner whereby Wear on the working part of the device is greatly lessened.

What is claimed is:

The combination with a fixed cylindrical supporting member having a uniform diameter throughout its entire length, of a member rotatably mounted on the supporting member and slidably adjustable therealong, and collars independently slidable on the supporting member and detachably secured in position thereon on opposite sides of said rotatable member, each of said collars extending over the ad acent edge of the supporting member and upon the face thereof, and anti-friction bearings disposedbetween the supporting member and the rotatable member and held in place by said collars but being removable laterally from said position when the collars are removed, said l5- GUSTAF ENARSON.
